摘要
用TG-DTG-DTA联用技术研究了金属簇合物犤(n-Bu)4N犦3犤WS4Ag3X3Br犦(X=Cl,Br,I)在动态氮气气氛中的热行为和热性质,通过对热分解过程中各步反应中间体的元素分析跟踪,判断了相应的分解组分;并结合其物质结构进行了讨论。对各步反应进行了动力学分析,并通过活化能和反应进程的依赖关系探讨了反应的复杂性。
The thermal behavior and properties of metal cluster compounds 3[WS4Ag3X3Br](X=Cl,Br,I) in a dynamic nitrogen atmosphere were studied by simultaneous TG DTG DTA technique. The probably expelled compositions in all the reaction stages were determined with help of elemental analysis for the intermediates during the processes; their thermal behaviors, meanwhile, were discussed in light of the chemical structure themselves. The thermal decomposition kinetics was investigated and the complexities of these processes were estimated based on the dependence of activation energy on extent of reaction.
